On April 20, 2010, British Petroleum’s Deepwater Horizon drilling rig in the Gulf of Mexico exploded, creating the largest oil spill in U.S. history. Analysis of 1,161 BP tweets during the crisis response reflected unexpected reputation repair strategies and responsibility attribution. Situational Crisis Communication Theory suggests that after an accident, PR messages typically reflect low responsibility attribution. Although the official investigation initially did not suggest a preventable crisis, 90% of BP’s tweets reflected high responsibility.
